Detailed Description

A class implementing calculation of the average plaquette.

This class computes the real trace of the plaquette averaged over the total number of plaquettes and the number of colours (which is three). Also computed is the variance of this mean, and one third of the real trace of the plaquette at the origin in the X-Y plane.

Member Function Documentation

void cps::AlgPlaq::run (  void   )

Performs the computation. The real trace of the plaquette is averaged over the lattice and normalised to unity. Postcondition: The following data are written to the file specified in the common_arg structure: mean plaquette variance of mean plaquette maximum plaquette minimum plaquette mean temporal plaquette mean spatial plaquette Definition at line 101 of file alg_plaq.C.
